Motion Control Software Engineer

The Giant Magellan Telescope is the most powerful ground-based telescope ever engineered. It was designed to push the boundaries of human knowledge and discover the unknown. With unmatched image quality, seven of the world’s largest mirrors will launch our view into the universe to uncover the cosmic mysteries of dark matter, investigate the origins of chemical elements, and search for signs of life on distant exoplanets for the first time.

The 30-meter class telescope is under construction at Las Campanas Observatory in Chile’s Atacama Desert, one of the best locations on Earth to view the heavens. From this unrivaled vantage into the southern sky, the Giant Magellan Telescope will produce the sharpest and most detailed images ever taken of our universe, ten times greater than the famed Hubble Space Telescope and four times the James Webb Space Telescope.

When complete in the late 2020s, the Giant Magellan Telescope will be the largest public-private funded science project in history. The endeavor was founded by an international consortium of leading universities and research institutions representing five countries, and is managed by the GMTO Corporation, a 501(c)(3) nonprofit organization based in Pasadena, California. Our culture is impactful, inclusive, and fearlessly innovative. We solve the most difficult engineering challenges and scientific questions with talented individuals who share a passion for revolutionizing humanity’s knowledge of the universe.

We invite you to join our team and leave your mark on astronomy’s future and beyond.

The Universe Awaits.

The Motion Control Software Engineer will be part of the Software and Controls (SWC) team and will be responsible to specify, design, implement and test the software for different motion control systems in the GMT telescope (mount control system, enclosure control system, etc.).
